Schemas are strictly typed definitions, used to infer TypeScript's type and data validation of an incoming request and outgoing response. Elysia's schema validation is based on Sinclair's TypeBox, a TypeScript library for data validation.

Can I use Zod for validation, since that's what the project is using Clent side already, or must I use t from Elysia?

Thanks for the prompt reply, however. The code sample by @sinclairzx81 You refered me to

...redacted excessive code...

TypeError: Right hand side of instanceof is not an object
at FromType (C:\Users\USER\Desktop\typebox\node_modules@sinclair\typemap\build\esm\typebox\typebox-from-zod.mjs:175:49)
at C:\Users\USER\Desktop\typebox\src\index.ts:13:13
at loadAndEvaluateModule (2:1)

Bun v1.2.20 (Windows x64)
What else can I do?

What else can I do?

It doesn't support zod@4 yet, use v3 for that

Other than that Elysia is built on Typebox and is not supporting other validators now

Thanks, this was really helpful

How can I have a response validator for 200 but keep the default for the other error codes?

{
      headers: headersValidator,
      query: searchValidator,
      response: {
        200: getAllResponseValidator,
      },
      beforeHandle({ headers, status }) {
        const apiKey = headers['x-api-key'];
        if (!apiKey) {
          return status(401);
        }

        const payload = jwtSigner.decode(apiKey);
        if (payload.role !== 'admin') {
          return status(403);
        }
      },
    }

For example, this wont work because, 401 and 403 just blow up errors.

Hey! Just found it out here: elysiajs/elysia#1164

Basically we can have a default field with this value: t.Ref('message') and everything works :)
